Haggen Grocery, the regional chain that ballooned from 18 stores to 164 when it took over a slew of Albertsons and Vons stores in December, has filed for Chapter 11 bankruptcy, City News Service reports. The big acquisition was troubled from the beginning; both buyer and seller have sued each other and Haggen announced plans last month to close or sell 27 stores, including one in Los Angeles County and several more in Southern California.
